CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 330,120,dated November10,1885.

Application filed April 11, 1885. Serial No. 161,975. (No model.)

To aZZ whom it may concern.-

Be it known that I LORENZO D. HOOVER, of Rock Island, in the county ofRock Island and State of Illinois, have invented a new and usefulImprovement in Oar-Couplers, of which the following is a full, clear,and exact description.

Reference is to be had to the accompanying drawings, forming apart ofthis specification, in which similar letters of reference indicatecorresponding parts in both the figures.

Figure 1 is a front elevation of a car-body having my new car-couplerapplied thereto, and Fig. 2 is a sectional elevation of one couplerretaining the link and a part of another with the coupling-pin elevatedto receive the link.

The invention will first be described in connection with the drawings,and then pointed out in the claims.

A represents the body of the car, to which the draw-head B may beattached in any suitable manner. The coupling-pin O, which is held in avertical chamber, D, in the drawhead, has the leg E pivoted to it,which, when the pin is raised, swings forward to rest upon thecross-piece or bridge F of the draw-head for holding the pin in elevatedposition, as shown at the left in Fig. 2. The cross-piece or bridge F isback of the aperture G, which receives the point or lower end, 0, of thecoupling-pin O, as shown at the right in Fig. 2, when the pin is loweredfor retaining the link H. The back of the chamber D is inclined from thetop of the draw-head downward and backward, so that the entrance of thelink H to the link-chamber I of the draw-head will force the lower endof the leg E off from the cross-piece F, so that the pin will drop ofits own weight through the link. The couplingpin is held in thedraw-head by a pin, b,

passed through the draw-head and through the slot (1, made in the pin.At the back of the pin to the draw-head, the pin may be locked inelevated position, as shown in the dotted lines at the left in Fig. 2.

The flanges c terminate in shoulders 0 that are adapted to rest upon theconnnectinglink, as shown at the right in Fig. 2, for holding the linkin horizontal position for coup ling.

The coupling pin may be raised in the draw-head from the top of the carby the chain K, or from either side of the car by the rod L, that hasthe levers L attached to its ends, and is connected to the pin by thecentral arm, L, so that the cars may be uncoupled without going betweenthem.

In coupling the cars it is only necessary to place the link in onedraw-head and elevate the pin in the other and back the cars together,the coupling being effected automatically by the link forcing the leg Ebackward off from the bridge orv cross-piece F, which permits the pointcof the pin to drop through the link, as above mentioned.

Constructed as described the coupler is not only automatic and certainin its action, but is cheap, strong, and durable.

Having thus described my invention,,I claim as new and desire to secureby Letters Patent- 1. The draw-head B, formed with the chan1- ber D, andbridge F, and aperture G, in combination with the coupling-pin 0, formedwith the shoulder 0 and provided with the pivoted leg E, the shoulder abeing adjusted to hold the connecting-link upon bridge F, substantiallyas shown and described.

2. The coupling-pin 0, formed with the flanges c and slot d, incombination with the leg E, pivoted to the pin between the flanges a,substantially as and for the purposes set forth.

3. The coupling-pin 0, formed with the flanges c", and provided with thepivoted leg E, in combination with the pawl J, pivoted to the draw-head,substantially as described, and for the purposes set forth.
